(Phys.org)—In an attempt to harvest the kinetic energy of airflow, researchers have demonstrated the ability to harvest energy directly from the vibrations of a flexible, piezoelectric beam placed in a wind tunnel. While ...

When a sound wave hits an obstacle and is scattered, the signal may be lost or degraded. But what if you could guide the signal around that obstacle, as if the interfering barrier didn't even exist? Recently, researchers ...

The structural properties of brittle materials like rock or ceramic, such as cracking under stress, have long been studied in detail, providing insight into avalanches, earthquakes and landslides. Wood and its response to ...
